/usr/libexec/qemu-kvm -S -M rhel6.3.0 -cpu Conroe -enable-kvm *-m
2048*-smp 4,sockets=1,cores=4,threads=1 -name

above example shows ~3 Gig VSZ but only 2048m are actually configured ...

if i'm not too blind and dumb :) ... 3030420 kb = 2959.39 mb ... and that's not what is configured as the VMs max allowed ram ...
